Design method for compression loaded NCF composites

Reference number
Funding from Vinnova SEK 2 504 000
Project duration November 2017 - December 2019
Status Completed
Venture National Aeronautical Research Program 7
Call 2017-02942-en

Purpose and goal

A method for predicting compressive failure has been successfully developed that includes measured fiber waviness and its impact on compressive strength. The method has first been demonstrated at coupon level and then applied at the component level. As a result of the project work, the Ph.D. student working in the project has obtained a his Ph.D. from Chalmers.

Expected results and effects

The methodology for fiber waviness analysis has been used on an aircraft engine of interest to GKN and has thus been able to compare the material against panels for material testing. The result is partly an ability to predict crime but also an increased understanding of what performance improvement is possible in the development of new material systems based on ´Non Crimp Fabric’-material.

Planned approach and implementation

The project has been an extension of a Ph.D. project where generated knowledge has been turned into increased product knowledge for GKN. Thanks to synergies with other initiatives at GKN, mechanical testing has been possible at a realistic component level and with support from RISE Sicomp high quality evaluation has taken place both during and after testing. Results have been analyzed and the use of Chalmers developed methodology has been shown.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
